| 8.2.1 | Network access
Network security involves two major components. The first is keeping your network safe from unauthorized access and the second is the ability to recover data from catastrophic events. The first part of security refers back to the network documentation section of the chapter. It involves making the network as secure as possible against unauthorized access. This is done by establishing security policies, such as minimum password length, maximum password age, unique passwords (not allowing the same password repeated), and only allowing the user to logon to the network at particular times of the day or days of the week. These parameters can be directly controlled by the network administrator and will be enforced by the network operating system. Security also involves making sure that users are aware of the company's network policies and follow those policies. Examples of such policies might be not letting users use family or pet names for passwords. Another example is making sure that the user is logged out of the network or has a password protected screen saver activated any time they leave their computer. These are the types of rules that can only be followed if the user understands and follows the established network policies.
